When fully developed, the park is expected to create more than 300 jobs.
The ARC grant and an expected $1 million in state economic development funds will help pay for extending water and sewer lines, and improving road access to the park, county officials said.
The park is located near Interstates 70 and 81 and CSX rail lines. Its accessibility to those two major transportation systems is a drawing card for industry, county officials said.
County Director of Economic and Community Development Robert Arch said rail lines have been extended to the Phillips and Purina plants, but it's not clear how or when the lines will be extended to other areas of the park, especially those on the other side of Hopewell Road.
Rail lines will have to be run across the road in order to serve industries that move there, Arch said.
"That's still being looked at from an engineering and design standpoint," he said. Funding for further rail extensions is "up in the air," he added.
County Engineer Terry McGee said the county has received preliminary approval from the state for the additional $1 million in economic development funds.
McGee said Newgate is part of a much larger planned project that encompasses 1,800 to 1,900 acres and is bordered by Md. 63 to the west, Hopewell Road to the east, Interstate 70 to the south and U.S. 40 and Md. 144 to the north.
This larger project is still in the study phase, McGee said. A consultant hired by the county is looking at the impact a large industrial complex would have on historical structures and on farmland, forest areas and wetlands, McGee said.
Another major issue is ownership. Some of the property the county wants to use for industrial development is in private hands, McGee said.
"Some we've talked to don't want to have anything to do with it. They say they want to continue farming," McGee said. "Others said they'd love it - they'd rather grow business than corn."
